CASH REGISTER AND INDICATOR.

SPECIFICATION forming part of Letters Patent No. 489,383, dated January 3, 1893.

Application tiled June 15,1892. Serial No. 436,825. (No model.)

To aZZ whom it may concern,.-

Be it known that I, MELVIN N. LOVELL, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsyl- Vania, have invented certain new and useful Improvements in Cash Registers and Indicators; and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in 1o the art to which it appertains to make and u`se the same.

This invention relates to cash registering and indicating machines, and consists in certain improvements in the construction ot the same,as will be hereinafter fully set forth and pointed out in the claims.

My present invention relates chiefly to that type or style of cash register and indicator shown and described in an application t'or a 2o patent now pending in the Patent Office, filed by me October 9, 1890, Serial No. 367,406; and While my present improvements may, many of them, be used on many of the Various types of machines for like purpose now in common z 5 use, it may, nevertheless, be said to be an improvement upon the class or type ot' machine shown and described in said application Serial No. 367,406.

The accompanying drawings illustrate my 3o invention as follows: 1 1

Figure l is a transverse vertical section through the middle of the machine on a line at right angles to the key-board, said line being indicated by the dotted line 3 3 in Fig.

5 3. Fig. 2 is a like view to Fig. l, with many important parts lett out and the scale en larged, and a changed position of parts is shown to illustrate the action ot the mechanism. Fig. 3 is a horizontal section taken on 4o the ledged plane indicated by the dotted line 5-5 in Fig. 5. Fig. 4 is a plan View ot' a few or" the registering wheels and indicating tablets drawn at about the size I prefer to make the said parts. Fig. 5 is an elevation of the .-15 rear of the machine with the rear case removed. Fig. 6 is a rear perspective View, partly in section and with only certain parts represented. Fig. 7 is a perspective view of a tablet-rod, a dog which acts upon the reg- 5o ister wheels and therear end of a key. Figs.

8 and 9 are perspective views of details for the purpose of illustrating the action, and will be explained fully hereinafter in place.

A, marks the case; D, the drawer; T, the indicating tablets; T the tablet rods; R and R the register wheels; C, the dogs which move the register wheels; K, the keys or key-levers;

B, the bell; B2 the bell hammer; and S, the drawer spring.

Other letters designating other parts will be 6o referred to in proper place.

Each key K, controls the movement of two register wheels R, R', which are journaled on the shaft R2. These wheels are each provided with thirtyteeth rand one of the wheels, R, is moved one notch or tooth at each movemeut ot' its actuating key while the other wheel, R', is moved one notch or tooth at every thirtieth movement of said key, or at each complete revolution of the wheel R. There- 7o fore I call the wheels R, the primary .wheels and the wheels R the secondary wheels.

There may be as my keys and sets ot' wheels as desired. I have used twenty-six keys, as follows: one cent, two cent, three cent, four cent, tive cent, ten cent, fifteen cent, twenty cent, twenty-five cent, thirty cent, thirty-Iive cent, -forty cent, forty-tive cent, fifty cent, fifty-five cent, sixty cent, seventy cent, eighty cent, ninety cent, one dollar, two dollar, 8o three dollar, four dollar, live dollar and ten dollar, and a drawer key, that is, a key for opening the drawer when it is not desired to register or indicate any amount. Each of these keys not only operate a pair of S5 register wheels R R but also operate a tablet when any of them are depressed and these tablets are each marked to correspond with the denomination ot' the key by which they are operated. The drawer key havingas go its designating sign a cypher. The object in having register Wheels in connection with the drawer key is to show the number of times the drawer has been opened for extra purposes.

By noting Fig. 4 it will be seen how the register wheels are marked. The primary wheel ot the one-cent key is marked 0, .01, .02, .03, lue. and the secondary wheel .30, .(30, .90, circ. The primary wheel of the two-cent key is roo marked 0, .02, .04, .06, .08, hc and the secondary wheel is marked .60, 1.20, 1.80, the. Above the wheels is a board L with grooves Z which receive the vertical tlanges of each pair of wheels, and the edge L of this board is the reading line; that is to say, the numerals on the wheels that are to be observed in order to ascertain the amounts registered by each wheel are those in proximity to the edge L of the board L. Hence when the machine is to be set for commencing work the 0 sign on each wheel should be brought into position at the edge of the board L. At'ter the machine has been used for a time, say one day, and it is desired to find the total amount. registered by the wheels it can be ascertained by adding up all the amounts displayed on all the wheels (except the drawer wheel) along the full length of the reading line.

rlhearrangement and general method of operation of the register wheels just described is the same as in my said former application. In this instance the wheels are made of cast metal in place of wood and the teeth r. are formed in the vertical llanges in place of being laterally extending pins. In the present instance, as in the former, the register wheels are held against untimely movement by spring catches or pawls Z at the upper side and a catch-pin k on the key. In addition to these stop devices I now provide a pawl-plate M, which is reacted by springs m at each end thereof. This plate can be seen in Figs. l, 2 3. It extends the hole length of the machine in front of the wheels, and when in normal position is in engagement with all the wheels and holds them uniformly in position. But when ever an y wheel is operated this plate is depressed until the acting tooth slips off of it, when it is reacted by the springs m. In Fig. 2 the parts are shown with one key nearly depressed to its limit, but not quite. The pawl plate M is shown as just about being disengaged by the acting tooth r, and the spring catch Z, is shown as nearly oft of a tooth. Then the key is depressed a little further the spring catch Z will drop in back of the tooth on which it is shown as resting and the spring plate M will slip o the tooth fr and iiy up against the next tooth and its spring action willhold the wheel R against its stops Z and Zt', and with its number spaces in line with all like spaces on the other wheels. This spring pawl plate acting when in normal position upon all the wheels prevents any wheel being moved out of place by frictional contact with an adjoining wheel, and it returns any register wheel to place that may be partially actuated. It will be seen in Fig. 2 that the teeth r of the wheels have their outer faces slanted back so thatthe pawl-plate M will be free to react as soon as it has passed from the front face of the tooth. This prevents the pawl-plate being carried past the next following tooth under any conditions of rapid action.

vThe wheels R and R are moved by the action of the dogs C and the dogs are moved by the direct action of the keys which also move the tablet rods. The form of the dogs is best shown in Figs. l, 2 and 7. They have two acting faces c2 and c3, one of which, c2, acts upon the teeth of the primary wheel R, and the other, c3, acts upon the teeth of the secondary wheel. The face c3 stands back of the face c2 and can only act upon the secondary wheel when the face c2 falls into the deep notch o" in the primary wheel. There is but one of these deep notches fr in each primary wheel and hence the secondary wheelis only moved once during each revolution of the primary wheel. Each dog has a notch c on its rear side near the bottom, and also a lug c2 below the notch which extends at right angles from the dog and across the tablet rod with which the dog is consorted. This construction is best seen in Fig. 7. The dogs when in normal position hang on the frame piece d, as seen in Figs. l and 2, which is grooved to receive them as shown in Figs. 3 and et at the upper lefthand corner thereof,said grooves being marked c4.

Each tablet-rod is guided in achannel-way formed by the frame pieces a, af, a2 and the vertical strips a3 (see Figs. l, 3 and et) and each dog lies within this channel-way by the side of the tablet-rod which is cut away below the shoulder t2 to admit it so that the dog and the tablet-rod stand side by side. On the lower end of each tablet-rod is a shoulder t* against which the key K contacts; above this is the shoulder t2 which rests on the dog when the parts are at normal, as seen in Fig. 7 most clearly. Vhen the key is depressed the tablet-rod is lifted, the shoulder t2 leaving the dog, and the tablet-rod alone is moved until the key contacts with the lower end of the dog, then the dog is carried with the rod but by contact with the key. The rods are limited in their upward movement by a stop pin t5 which contacts with the shoulder Z on the rod, and they are held up by a spring catch 15G which passes and gets below the catch on the rod. The keys are limited by the outer ends contacting with the frame baseA (see Fig. l) but they are not held depressed by any device. The dogs are held up by means to be hereinafter explained. The object in having the tablet-rods move through a greater space than the dogs is that only a limited degree of movement of the dogs is required to move the register wheels one notch or tooth, while in order to display a tablet of sufficient size to make the indication clear it must move much farther than it is necessary to move the dog. In my application above referred to this extra movement of the rod was provided for, but in that case the dog was carried by the rod, while in this case the dog and rod are each carried independently by the key and each has separate means for holding it up and releasing it.

As stated above, the rods are held up bythe spring catches t6 engaging with the catch lugs IOO IIO

t. These spring catches t6 are all supported by asliding bar H, and when this bar is moved longitudinally any supported tablet-rod is re leased.- The arrangement is such that the bar H is moved longitudinally whenever a key is depressed, hence the last indicated amount is continued until the next yamount is to be indicated. Thus, if the last sale was tive cents, the iive cent tablet will remain displayed until the next sale is to be indicated, and if that is ten cents, then the ten-cent tablet will be displayed and the tive-cent tablet will simultaneously disappear, for the movement which brings up the ten cent tablet moves the bar H and releases the tive-cent .tablet The means for moving the bar H, are connected with and operated by the means which engages and disengages the dogs and will be explained in connection therewith, as follows:

At the rear of the machine is a gate, G, which extends across the whole length of the machine and when in its normal position, lies directly over the extreme ends k of the keys K. This is shown in Figs. l, 2, 5 and 6. In Figs. l and 6 it will be seen that this gate G, is T-formed; that is, it has an upward extension G at its middle which is notched and tits in gnideblocks g and is held in place by a cross-piece g. Whenever any key is depressed this gate is raised. At the upper end of the part G on the inside thereof is a pin h', which, when the gate goes up, contacts with a cam h on the bar H, and moves that bar longitudinally. As soon as the pin passes the cam the bar reacts by the action of a spring not shown, which it carries. This re-r action takes place before the gate has reached its upward limit and, hence, before the talolet' rod, carried by the key which moves the gate also, has reached its upward limit, and, consequently, the tablet-rod that was last raised is released by the longitudinal movement of the bar II, while the gate is being raised, and is reacted into position to allow the proper spring catch t, to act to engage the tablet rod which is being carried up with the gate before the gate reaches its upward limit of movement. Vhen the gate de scends the pin h passes down on the opposite side Of the cam h from that against which it acted when going up, and the Acam is pivoted and held in normal position by a spring h2 (see Fig. 5) which spring is overcome when the cam is pushed back by the pin h when the gate is going down. Immediately in front of the gate G, is a parallel bar I which is hung, by arms extending from its ends, on pivots on the frame posts, as clearly shown in Fig. 6. 'This bar is seen in its normal position in Fig. l, in cross section, and in its active position in Figs. 2 and 6. When the gate G is elevated to its upper limit, as shown in Figs. 2 and 6, the bar I, which I call a dogbar, is engaged by hooks g4, on the gate and held in a horizontal position and when in that position it sets under the lower end of the dog that is elevated and thus holds it up and it sets into the notches c in all the other dogs and holds them against being moved. Hence, while the gate G, is in an elevated position, it is impossible to operate any of the other dogs or move any ot' the keys operatively. The gate G has a bar G2 extending down from it near its middle and near its lower end is a notch g5 which is engaged by a catch-lever D3 when the gate reaches its upward limit, and the gate will be held up by this catch device until it is released, and this will occur when the drawer is closed.

All the various parts of the machine, except the last tablet displayed and its rod, are at normal when the drawer is closed. When a key is depressed to its limit the drawer is released and thrown open bya spring S. Then those parts which have just been operated may be said to be in action and while they are thus no other keys and consorted parts can be actively operated until the drawer is closed, which will bring all the parts just in action to normal, except the tablet and its rod. In Fig. l

the parts are shown at normal, that is, as they are when the drawer is closed. It will be seen that a catch D on the back ot' the drawer is in engagement with a'catch-bar or trigger D2 which is pivoted at d2 to a lug on the frame work. The rear end of the trigger D2 extends through a slot g3 in the bar G2 that is connected with the gate G. When the gate G is raised to its limit the trigger is struck by the bottom of the slot g3 and lifted up and this disengages the catch and allows the drawer to open by the action of the spring S. On the back of the drawer there is a lug D4 in which is pivoted a nger D5 which has a rounded side (see Fig. 9). Back of this device is the catch lever D3 above referred to, which engages the notch g5 in the gate-bar G2 and holds the gate. up. This lever is pivoted at d2 on the frame work. Vhen the drawer is closed the finger D5 pushes the lever D3 to one side and thereby releases its engagement with the bar G2 and thus allows the parts to return to normal. The jfinger D5 when the drawer is closed, falls into a notch in the lever D3, and when the drawer is opened it turns on its pivot on the lug D4 and thus escapes the lever D3 and is again ready for action upon that lever, as seen in Figs. 6 and 9.

On the side oit the bar G2 is a pivoted notched cam N, which, as the gate is moving up with the bell-lever B and pushes it back, but before the gate G reaches its upper limit the cam N passes the lever B and allows it to react by its spring h, and the bell is sounded. The cam N is pivoted so as to escape the lever B when the gate is descending. A spring, not shown, holds the cam N in normal position. The cam N is notched on its acting face and the lever B has its contacting face pointed so as to engage said notches. The object of this is to hold the gate G against reaction at all points in its upward movement until the lever B passes below the cam N and IOO IIO

then the lever D3 engages the bar G2 and holds the gate up as above stated.

In Fig. 8 the cam N is shown engaging the lever B as the gate is partially elevated, and in Fig. 6 the camN is shown as havingpassed over the lever B and released it.

It is not necessary that there be more than one or two notches in the cam N, and these should be at its lower end so as to lock the gate against reaction as soon as the dog-barI has been lifted into a horizontal position, where it locks all the dogs, except the moving dog, against movement, and it locks the moving dog against reaction. But I have shown the cam N, as having many notches and when so made the gate can not be reacted after it has been moved a little way up, but if the operator discovers that he is operating a wrong key he can change to the proper key any time before the deg bar I, has been brought into active position. If the cam N, has only one or two notches at its lower end in proper relative position to hold the gate against reaction after the dog-bar had been brought into action, then in case the operator found it necessary to correct his action before he had gone too far he could do so, but the gate G, would be lowered with the abandoned key and then moved up again with the newly used key. Hence all that is effected by the surplus number of notches in the cam N, is to prevent the gate from moving back if a change of keys is desired, and this is of no great moment.

As soon as a key has been used and the gate is up and the dogs are locked, that key, as well as all the others, is free. The keys are at no time locked, but the dogs are locked,

and hence the keys become inoperative to the extent that they can not move the registering mechanism until the drawer is closed and the parts are brought back to normal.
